Ketone derived from diacetone-α-D-glucose is a suitable starting material for the synthesis of 3-C-linked glycohybrids containing 1,2,3-triazole moiety as an intersugar linkage. The pyranose tautomers of 3-deoxy-3-(1,2,3-1H-triazol-1-yl)glucose, 3-C-[(1,2,3-1Htriazol-1-yl)methyl]allose and 3-C-[(1,2,3-1H-triazol-1-yl)methyl]gulose moieties are released upon the acidic hydrolysis of the corresponding
衍生自双丙酮-α-D-葡萄糖的酮是用于合成含有1,2,3-三唑部分作为糖间键的3- C-连接的糖杂的合适原料。3-脱氧-3-(1,2,3-1 H-三唑-1-基)葡萄糖,3- C -[(1,2,3-1 H三唑-1-基)甲基]的吡喃糖互变异构体相应的O-异亚丙基保护的呋喃糖基型合成中间体经酸水解后,会释放出半乳糖和3- C -[((1,2,3-1 H-三唑-1-基)甲基)古洛糖部分。一些标题化合物显示出罕见的激活大肠杆菌β-半乳糖苷酶的特性。
